Description

[0001] The present invention relates to a cleaning device for cleaning radiators and heat-transferring surfaces, in particular panel radiators, according to the preamble of claim 1.

[0002] Panel radiators consist of several heating plates made of steel or other materials through which a heating medium flows. Between the heating plates, several metal sheets, known as convection fins, can be installed. These fins absorb heat from the heating plates and warm the air flowing through the radiator via convection, thus significantly increasing the proportion of heat emitted by convection. Often, the heating plates and convection fins form a finned structure, which increases the surface area. Due to the large surface area of ​​the heating plates and convection fins, panel radiators emit the majority of their heat through convection.Panel radiators with convection plates can be operated with particularly low flow temperatures due to the significant increase in surface area, while at the same time the difference between the flow and return temperatures can be kept particularly high, thus guaranteeing economical operation for a heat generator regardless of the fuel used, such as natural gas, heating oil or electricity.

[0003] Dirt and dust particles that accumulate on the heating plates and convection plates over time reduce the heat output of the panel radiators to the ambient air, which significantly reduces the efficiency of the panel radiators, necessitates increased fuel consumption, and consequently increases CO2 emissions.

[0004] Besides the deterioration of the indoor climate due to reduced heat output, such soiling poses a significant health risk for people with dust allergies, especially at the beginning of the heating season when air circulation stirs up dirt and dust particles. These dirt and dust particles also settle on furniture, creating an additional burden in the form of dust deposits.

[0005] German patent DE 10 2020 105 740 A1 discloses a device for cleaning a radiator, comprising an upper frame and a lower frame, each completely covering the radiator's horizontal end faces. A cleaning fluid is introduced into the radiator via the upper frame, collected by the lower frame, and extracted. To prevent the fluid from leaking into the surrounding area, the upper and lower frames must be fitted as tightly as possible onto the radiator. A casing element surrounding the radiator's sides and positioned between the upper and lower frames prevents lateral leakage of the fluid. Due to the water requirement, the device is heavy and has a complex design. Furthermore, the cleaning process, involving the attachment of the casing element, is particularly time-consuming and can lead to moisture damage, for example, if water leaks onto a wooden floor.

[0006] A device for cleaning radiators is known from DE 201 09 287 U1. The device comprises a blower and suction unit connected via a flexible tube to an air nozzle and a suction nozzle. The air nozzle is placed on top of the radiator and the suction nozzle on bottom of the radiator in such a way that the air nozzle and the suction nozzle completely cover the radiator in the width direction and partially cover it in the length direction. Since the air nozzle and the suction nozzle only cover a portion of the radiator, sealing tabs are inserted through the radiator in front of and behind the air and suction nozzles to ensure an airtight connection between them. In this way, a completely closed airflow can be achieved for cleaning the radiator. Following cleaning with the airflow, steam treatment is carried out.To completely clean the radiator, after partial cleaning, the sealing tabs must be removed, the air and suction nozzle repositioned, and the sealing tabs reinserted through the radiator. These steps are repeated until the entire length of the radiator has been cleaned.

[0007] Cleaning radiators with known cleaning devices is particularly complicated and very time-consuming. If the radiator is located under a windowsill or in radiator recesses, cleaning using this method is either impossible or extremely difficult. The present invention aims to provide a cleaning device for radiators that enables quick and particularly easy cleaning.

[0008] The above problem is solved by a cleaning device according to claim 1. Advantageous embodiments are the subject of the dependent claims.

[0009] The proposed cleaning device is designed for cleaning a radiator, including one with convection fins. The cleaning device includes a compressor unit for generating an airflow by means of overpressure, with an air nozzle unit connected to the compressor unit for directing the compressed air into the radiator. The air nozzle unit is either mounted on or positioned at a distance from the upper flat surface of the radiator. The air nozzle unit only partially covers the upper flat surface in the longitudinal and / or transverse direction.

[0010] The cleaning device further comprises a suction device for extracting air and / or air containing contaminants, such as dust particles, that are dislodged during the cleaning process, by means of a vacuum. The cleaning device also includes an extraction system connected to the suction device for extracting air and / or air containing contaminants, such as dust particles, that are dislodged during the cleaning process from the radiator. The extraction system is either mounted on or attached to the lower flat surface of the radiator, or it is positioned at a distance from the lower flat surface of the radiator. The extraction system covers the lower flat surface only partially, either longitudinally and / or laterally.

[0011] The cleaning device is preferably designed for the dry cleaning of radiators.

[0012] According to a first aspect of the present invention, an air cleaning flow generated during cleaning between the air nozzle unit and the suction unit within the radiator is open at least on one side, at least partially, in the longitudinal and / or transverse direction of the radiator. This enables particularly quick and easy cleaning of the radiator. In particular, it is then unnecessary to route components of the cleaning device according to the invention through the radiator to create a closed airflow between the air nozzle unit and the suction unit. Rather, it is sufficient to place the air nozzle unit on the upper flat side of the radiator and the suction unit on the lower flat side of the radiator to begin cleaning.

[0013] According to a further aspect of the present invention, which can also be implemented independently, the air nozzle unit and / or the suction unit for cleaning the radiator is / are movable, in particular shiftable, along the entire length of the radiator in the longitudinal and / or lateral direction. The radiator can then be cleaned in a particularly simple manner by moving the air nozzle unit and / or the suction unit, in particular simultaneously, along the entire length or lateral extent of the radiator. It is then possible to achieve quick and easy cleaning of the radiator using compressed air and suction with an air nozzle unit that is small compared to the upper flat side of the radiator and a suction unit that is also small compared to the lower flat side of the radiator.

[0014] According to a further aspect of the present invention, which can also be implemented independently, the air nozzle unit and the suction unit are held by a common holding device, wherein the holding device is telescopic for adjusting the distance between the air nozzle unit and the suction unit. With the aid of the holding device, the air nozzle unit and the suction unit can be held together and simultaneously moved together in the longitudinal and / or lateral direction of the radiator, thereby enabling particularly quick and easy cleaning. The holding device allows for particularly simple adjustment of the distance between the air nozzle unit and the suction unit.

[0015] The cleaning device preferably has a functional unit that is movable on wheels, preferably similar to a suitcase or trolley, and which includes the compressor and suction units. This allows the cleaning device to be transported particularly easily with minimal effort. The components with a comparatively high weight and space requirement, the compressor and suction units, are then integrated into the functional unit, resulting in particularly good handling of the cleaning device.

[0016] The mounting bracket and the functional unit are preferably connected via a flexible hose. This allows the mounting bracket to be moved freely and independently of the functional unit, further simplifying radiator cleaning. The mobility and handling of the mounting bracket are thus limited only by the length and flexibility of the hose.

[0017] Preferably, the air nozzle unit and the compressor unit are connected to each other, at least partially, via a flexible pressure hose. Alternatively or additionally, the extraction system and the suction unit are connected to each other, at least partially, via a flexible vacuum hose. Due to the flexible design of the pressure hose and / or the vacuum hose, the air nozzle unit and / or the extraction system can be moved relative to the compressor unit and / or the suction unit, respectively, in a particularly easy manner.

[0018] It is particularly advantageous if the compressor unit is connected to the mounting device via the flexible pressure hose, and the mounting device connects the air nozzle unit to the flexible pressure hose. The mounting device is then designed as a multifunctional element that holds the air nozzle unit and connects it to the flexible pressure hose.

[0019] Preferably, the suction device is connected to the holding device via the flexible vacuum hose, and the holding device connects the suction device to the flexible vacuum hose. The holding device is then designed as a multifunctional element that, in addition to holding the suction device, also serves to connect the suction device to the flexible vacuum hose.

[0020] The cleaning device preferably further comprises a control unit for regulating and controlling the compressor and / or the suction unit. Preferably, the output of the compressor and / or the output of the suction unit is / are manually and / or automatically adjustable by means of the control unit. The compressor and / or the suction unit can then be manually and / or automatically adapted to the radiator being cleaned in order to achieve optimal cleaning results for that radiator.

[0021] The control unit is preferably connected to a control panel of the cleaning device for manual adjustment of the compressor and suction units, thus enabling particularly simple manual input. Preferably, the control unit is part of the movable functional unit.

[0022] In particular, one of the parameters – compressor output and suction output – can be manually and / or automatically adjusted to the other parameter by means of the control unit. In this way, by setting one of the aforementioned parameters, the other parameter can be adjusted, especially manually. This ensures that the cleaning device operates within an optimal range of the adjustable parameters.

[0023] Preferably, the control device is designed to adjust the output of the compressor and / or the output of the suction unit depending on the distance between the suction unit and the air nozzle unit. If the distance between the suction unit and the air nozzle unit is changed to clean a taller radiator—that is, a radiator with a greater vertical extent—the output of the compressor and the output of the suction unit can be adjusted automatically and / or manually. In this way, an optimal cleaning result can be achieved regardless of the size of the radiator.

[0024] It is particularly advantageous if the holding device has a control element for controlling, especially for starting and stopping, the compressor and / or suction device. This makes it possible to carry out the cleaning process using the control element without the user having to make any adjustments to the functional unit, thus further simplifying the cleaning process and allowing the user to concentrate on the cleaning task.

[0025] It is particularly advantageous if the control element is designed to start the suction device first and then the compressor device during a cleaning process. This prevents dirt and / or dust particles from being stirred up by the compressed air and escaping into the environment without being extracted by the suction system.

[0026] Preferably, the control element is designed to first switch off the compressor and then the suction device to end a cleaning process. This prevents dirt and / or dust particles from being stirred up by the compressed air and escaping into the environment without being extracted by the suction system.

[0027] To optimally adapt the cleaning device to the size of the radiator, the suction unit and / or the air nozzle unit are preferably detachably connected to the mounting bracket, allowing the air nozzle unit and the suction unit to be interchangeable depending on the radiator being cleaned. This allows the selection of an air nozzle unit and / or suction unit with a suitable width to completely cover the radiator. During the cleaning process, the air nozzle unit and the suction unit then simply need to be moved lengthwise along the entire length of the radiator to achieve even cleaning.

[0028] It is also possible for the air nozzle unit and / or the extraction system to be individually telescopically adjustable in the width of the radiator. This allows the air nozzle unit and / or the extraction system to be easily adapted to different radiators with varying widths.

[0029] Additional advantages, features, properties, and aspects of the present invention will become apparent from the claims and the following description and a preferred embodiment with reference to the drawing. It shows: Fig. 1 a schematic view of a proposed cleaning device for cleaning a radiator with a functional unit and a holding device connected to the functional unit during a cleaning process; Fig. 2 a schematic view of the holding device with an air nozzle unit and a suction system during a cleaning process; Fig. 3. A perspective view of the holding device during a cleaning process; Fig. 4A a top view of the air nozzle unit; and Fig. 4B a top view of the extraction system.

[0030] In the figures, the same reference symbols are used for identical or similar parts, achieving corresponding or comparable advantages even if a repeated description is omitted for the sake of simplicity.

[0031] Fig. Figure 1 shows a schematic view of a proposed cleaning device 1 for cleaning radiators 2, in particular panel radiators.

[0032] The cleaning device 1 is preferably designed for the dry cleaning of radiators 2.

[0033] The cleaning device 1 preferably has a compressor device 3 for generating an air volume flow with an overpressure.

[0034] Preferably, the overpressure that can be generated by the compressor device 3 is more than 0.03 MPa and / or less than 1 MPa, preferably more than 0.1 MPa and / or less than 0.9 MPa, further preferably more than 0.3 MPa and / or less than 0.8 MPa.

[0035] Furthermore, the cleaning device 1 preferably has an air nozzle unit 4 which is connected to the compressor unit 3. Preferably, the air nozzle unit 4 is designed to introduce the air volume flow into the heating element 2.

[0036] The air nozzle unit 4 is preferably mounted on the upper flat side 2a of the radiator 2 or can be attached to the upper flat side 2a of the radiator 2. It is also possible that the air nozzle unit 4 is provided at a distance from the upper flat side 2a of the radiator 2.

[0037] The term "upper flat side" refers in this case to the installed state of the radiator and thus denotes the vertically higher horizontal flat side of the radiator.

[0038] The term "spaced" preferably means that there is a vertical distance of less than 50 mm, more preferably less than 30 mm, and more preferably less than 15 mm between the air nozzle unit 4 and the upper flat side 2a.

[0039] The air nozzle unit 4 is preferably to be placed on the upper flat side 2A of the radiator 2 from above, i.e. in the direction of gravity, and / or perpendicular to it.

[0040] If the air nozzle unit 4 is placed on the upper flat side 2a, the air nozzle unit 4 covers the upper flat side 2a preferably only partially in the longitudinal direction L and / or in the lateral direction B.

[0041] During a cleaning process, the air nozzle unit 4 is preferably positioned against the upper flat side 2a or is provided or arranged at a distance from the upper flat side 2a.

[0042] The term "longitudinal direction" refers here to the longer of the two horizontal directions of extension of radiator 2 in its installed state. Thus, the term "lateral direction" refers to the shorter of the two horizontal directions of extension of radiator 2 in its installed state.

[0043] Preferably, the air nozzle unit 4, when placed on the upper flat side 2a, completely covers the upper flat side 2a in the width direction B, as shown. Fig. 1, Fig. 3 and Fig. Show 4A.

[0044] To prevent the air nozzle unit 4 from slipping in the lateral direction B relative to the radiator 2, the air nozzle unit 4 preferably has two projections 4a between which the radiator 2 can be received, as shown. Fig. 1 and Fig. 3 shows.

[0045] The air nozzle unit 4 preferably covers the upper flat side 2a in the longitudinal direction L only sectionally, as in particular Fig. 2 shows.

[0046] However, the reverse case is also possible, in which the air nozzle unit 4, when in place, only partially covers the upper flat side 2a in the width direction B and completely covers it in the length direction L.

[0047] It is also conceivable that the air nozzle unit 4 only partially covers the upper flat side 2a in the width direction B and in the length direction L.

[0048] The air nozzle unit 4 can have exactly one air outlet valve or air outlet, or several air outlet valves or air nozzles. This allows for a uniform supply of air to the radiator 2.

[0049] Preferably, the air outlet valve(s) is / are not variable and / or has / have, in particular, a non-variable outlet cross-section.

[0050] However, it is also possible to design the air outlet valve(s) to be adjustable. For example, the outlet cross-section can be made adjustable.

[0051] The cleaning device 1 also preferably has a suction device 5 for extracting air under negative pressure.

[0052] The suction device 5 is preferably designed to generate a pressure difference of more than 20 kPa, preferably more than 25 kPa, and more preferably more than 30 kPa.

[0053] Furthermore, the cleaning device 1 preferably has a suction port 6 which is connected to the suction device 5. Preferably, the suction port 6 is designed to extract air and dirt particles loosened during the cleaning process from the radiator 2.

[0054] The extraction system 6 is preferably placed on or mounted on the lower flat side 2b of the radiator 2 or can be provided or made available at a distance from the lower flat side 2b of the radiator 2.

[0055] The term "lower flat side" refers in this case to the installed state of the radiator and thus denotes the lower horizontal flat side of the radiator.

[0056] The term "spaced" preferably means that there is a vertical distance of less than 50 mm, more preferably less than 30 mm, and more preferably less than 15 mm between the extraction point 6 and the lower flat side 2b.

[0057] The extraction system 6 is preferably to be placed on the lower flat side 2b of the radiator 2 and / or perpendicular to it from below, i.e. against the direction of gravity.

[0058] During a cleaning process, the suction device 6 is preferably positioned against the lower flat side 2b or is provided or arranged at a distance from the lower flat side 2b.

[0059] If the extraction unit 6 is placed on the lower flat side 2b, the air nozzle unit 4 only partially covers the lower flat side 2b in the longitudinal direction L and / or in the lateral direction B. In this way, the extraction unit 6 can be kept particularly small.

[0060] Preferably, the extraction system 6, when in place, completely covers the lower flat side 2b in the width direction B, as Fig. 1 and Fig. 4B show, and in the longitudinal direction L only section by section, as Fig. Figure 2 shows. However, a reverse arrangement is also possible, in which the extraction system 6, when in place, only partially covers the lower flat side 2b in the width direction B and completely covers it in the length direction L.

[0061] Slippage of the extraction system 6 in the lateral direction B relative to the radiator 2 can be prevented if the extraction system 6 has two projections 6a between which the radiator 2 can be accommodated, as shown. Fig. 1 and Fig. 3 shows in detail.

[0062] The extraction system 6 can have exactly one air inlet valve or air entry point, or several air inlet valves or air entry points (extraction). This allows for a uniform extraction of air from the radiator 2.

[0063] Preferably, the air inlet valve(s) is / are not variable and / or has / have, in particular, a non-variable outlet cross-section.

[0064] However, it is also possible to design the air intake valve(s) to be adjustable. For example, the outlet cross-section can be made adjustable.

[0065] The following description focuses on the air nozzle unit 4 and the extraction system 6 in the embodiment where the air nozzle unit 4 completely covers the upper flat surface 2a in the width direction B and only partially covers it in the length direction L, and the extraction system 6 completely covers the lower flat surface 2b in the width direction B and only partially covers it in the length direction L. The following description preferably applies analogously to cases where the air nozzle unit 4 and the extraction system 6 only partially cover the upper or lower flat surface 2a or 2b in the width direction B and in the length direction L, or where they only partially cover the upper or lower flat surface 2a or 2b in the width direction B and completely cover it in the length direction L.

[0066] The air volume flow generated by the compressor unit 3 can be directed at positive pressure from above into the radiator 2 via the air nozzle unit 4. A negative pressure is created on the underside of the radiator 2 via the extraction port 6. In this way, an air purification flow can be established between the air nozzle unit 4 and the extraction port 6. This air purification flow can entrain dirt and dust particles, which are then extracted along with the air purification flow via the extraction port 6.

[0067] The suction device 5 preferably further comprises a collection container 7 with a particle filter, through which dirt and dust particles extracted by the suction unit 6 can be collected. The extracted dirt and dust particles are then safely collected and stored and, in particular, are not released into the environment.

[0068] Preferably, the cleaning device 1 or the suction device 5 meets dust class M or H according to DIN EN 60335-2-69, thus minimizing the burden on allergy sufferers during and after cleaning. A cleaning device 1 designed in this way is particularly suitable for commercial use.

[0069] Preferably, the air cleaning flow generated during the cleaning of the radiator 2 is open at least partially on at least one side in the longitudinal direction L of the radiator 2. In this way, an air flow that is open at least partially in at least one horizontal direction can be generated within the radiator 2, enabling particularly efficient and simple cleaning of the radiator 2. For a particularly good cleaning result, it is then not necessary to connect the air nozzle unit 4 and the extraction unit 6 airtight through the radiator 2, thus achieving a particularly fast yet thorough cleaning of the radiator 2.

[0070] During the cleaning of the radiator 2, the air cleaning flow generated between the air nozzle unit 4 and the extraction unit 6 is preferably limited within the radiator 2 in the lateral direction B by the side walls 2c of the radiator 2. It is then impossible for the air volume flow to escape the radiator 2 in the lateral direction B. The air volume flow can thus be limited in the lateral direction B. At the same time, it can be prevented or at least substantially reduced that dirt and dust particles escape the radiator 2 in the lateral direction B and enter the environment.

[0071] It is particularly advantageous if the air nozzle unit 4 and the extraction system 6 for cleaning the radiator 2 are movable, in particular displaceable, in the longitudinal direction L over the entire longitudinal extent of the radiator 2 ( Fig. 2) Cleaning the radiator 2 can then be carried out in a particularly simple and quick manner by moving the air nozzle unit 4 and the suction unit 6 longitudinally L along the entire length of the radiator 2. In particular, it is then not necessary for the air nozzle unit 4 and / or the suction unit 6 to completely cover the upper or lower flat side 2a, 2b of the radiator 2 in order to achieve complete cleaning of the radiator 2.

[0072] It is particularly advantageous if the air nozzle unit 4 and the extraction unit 6 are held by a common holding device 8. The air nozzle unit 4 and the extraction unit 6 can then be moved together very easily during cleaning using the holding device 8.

[0073] It is particularly advantageous if the holding device 8 for adjusting the distance between the air nozzle unit 4 and the extraction unit 6 is telescopic. It is then particularly easy to adjust the distance between the air nozzle unit 4 and the extraction unit 6 to the respective height – the extension in the vertical direction H – of the radiator 2 to be cleaned. Fig. 1, Fig. 2 and Fig. 3).

[0074] The holding device 8 can be continuously adjustable and / or adjustable in predefined steps.

[0075] Preferably, the holding device 8 can be locked after setting a distance between the air nozzle unit 4 and the suction unit 6, so that the distance between the air nozzle unit 4 and the suction unit 6 cannot be changed without releasing the locking mechanism.

[0076] After a cleaning process, the locking mechanism can then be released to change the distance between the air nozzle unit 4 and the suction unit 6, ensuring easy removal after the cleaning process.

[0077] Particularly preferably, the air nozzle unit 4 and the extraction unit 6 are arranged vertically one above the other during the cleaning process, so that the air nozzle unit 4 is positioned directly above the extraction unit 6. In this way, a substantially vertical air cleaning flow can be generated within the radiator 2.

[0078] Particularly preferably, the air nozzle unit 4 and the extraction unit 6 have the same extent in the lateral direction B and / or in the longitudinal direction L.

[0079] The air nozzle unit 4 and the extraction unit 6 preferably have the same coverage of the radiator 2. In this context, "coverage" refers to the area of ​​the upper end face 2a or the lower end face 2b covered by the air nozzle unit 4 or the extraction unit 6. The air nozzle unit 4 and the extraction unit 6 then have the same extent in the width direction B and the length direction L.

[0080] How Fig. As shown in Figure 1, the cleaning device 1 preferably has a functional unit 10 that is movable on at least one roller 9, thereby enabling particularly easy transportability of the cleaning device 1. The functional unit 10 can then be easily pulled and / or pushed and / or lifted and / or moved in a manner similar to a suitcase or trolley.

[0081] How Fig. As further shown in Figure 1, the functional unit 10 preferably comprises the compressor unit 3 and the suction unit 5. The functional unit 10 then includes the components with comparatively high weight and space requirements, namely the compressor unit 3 and the suction unit 5, which makes them particularly easy to transport.

[0082] Preferably, the receiving container 7 is also part of the functional unit 10.

[0083] The cleaning device 1 can be powered by an energy storage device 11, such as a battery. If the cleaning device 1 has an energy storage device 11, this is preferably part of the functional unit 10. An energy storage device 11 enables the cleaning of radiators 2 even without access to a power grid. At the same time, moving between rooms to clean multiple radiators 2 can be done particularly quickly and easily.

[0084] Preferably, the cleaning device 1 has a connector 12 for a household electrical supply, particularly as part of the functional unit 10. The connector 12 is particularly suitable for a type-C socket. The connector 12 is preferably designed as a Schuko plug, a Europlug, a contour plug, or a hybrid plug.

[0085] It is preferably possible to charge the energy storage unit 11 and / or supply the cleaning device 1 with sufficient energy to clean radiators 2 via the connection plug 12. However, the energy storage unit 11 is not strictly necessary and is merely an option.

[0086] How Fig. 1 and Fig. As shown in Figure 2, the holding device 8 is preferably connected to the functional unit 10 via a flexible hose 13. The holding device 8 is preferably freely movable relative to the functional unit 10, the mobility preferably being limited only by the length, flexibility, and bending radius of the flexible hose 13.

[0087] The air nozzle unit 4 and the compressor unit 3 are preferably connected to each other, at least partially, via a flexible pressure hose 14. The flexible pressure hose 14 can be directly coupled to the air nozzle unit 4 and the compressor unit 3.

[0088] It is particularly advantageous if the flexible pressure hose 14 is coupled to the compressor unit 3 and the holding device 8. The holding device 8 then preferably forms a compressed air channel 15 between the compressor unit 3 and the flexible pressure hose 14, as shown. Fig. 1 shows.

[0089] The extraction unit 6 and the suction device 5 are preferably connected to each other, at least partially, via a flexible vacuum hose 16. The flexible vacuum hose 16 can be directly coupled to the extraction unit 6 and the suction device 5.

[0090] It is particularly advantageous if the flexible vacuum hose 16 is coupled to the suction device 5 and the holding device 8. Preferably, the holding device 8 has a vacuum channel 17 for connecting the suction unit 6 and the flexible vacuum hose 16.

[0091] The flexible pressure hose 14 and / or the flexible vacuum hose 16 is / are preferably guided through the flexible hose 13, so that, viewed from the outside, only one hose, in this case the flexible hose 13, extends from the functional unit 10 to the holding device 8.

[0092] The cleaning device 1 further preferably has a control and regulating device 18 for regulating and controlling the compressor device 3.

[0093] The control and regulating device 18 is specifically designed to start and / or stop the compressor device 3.

[0094] Furthermore, the output of the compressor unit 3 can be adjusted, preferably manually and / or automatically, by means of the control unit 18. In this way, the output of the compressor unit 3 can be adapted to the size and design of a radiator 2 to be cleaned.

[0095] Alternatively or additionally, it may be possible to adjust the generated overpressure and / or the generated air volume flow manually and / or automatically using the control device 18. Preferably, the air volume flow and / or the air pressure or overpressure can be adjusted with a pressure reducer, in particular to the respective, different sizes of radiators 2.

[0096] The control and regulating device 18 is designed as an alternative or additional function for the control and regulating of the suction device 5. The control and regulating device 18 is specifically designed to start and / or stop the suction device 5 and / or to adjust the power of the suction device 5 manually and / or automatically.

[0097] Alternatively or additionally, it is preferably possible to adjust the negative pressure and / or the extracted air volume flow generated by the suction device 5 manually and / or automatically using the control device 18. The generated negative pressure and / or the extracted air volume flow can preferably be adjusted by means of a pressure reducer. This makes it possible, for example, to adjust the generated negative pressure and / or the extracted air volume flow to the respective different sizes of radiators 2.

[0098] The control and regulating device 18 is particularly preferably connected to a control panel 19 of the cleaning device 1 for the manual adjustment of the compressor unit 3 and the suction unit 5. The aforementioned parameters can be manually adjusted by an operator directly on the cleaning device 1 via the control panel 19. For this purpose, the control panel 19 is connected to the control and regulating device 18 via a signal connection, in particular an electrical one. It is particularly advantageous if the control panel 19 visually displays the values ​​of the set parameters to the user or is designed to display the values ​​of the set parameters to the user.

[0099] A user can preferably start and / or stop the compressor unit 3 by manual input via the control panel 19. This preferably makes it possible to manually adjust the power of the compressor unit 3 via the control panel 19.

[0100] In addition, it may alternatively or additionally be possible to adjust the overpressure and / or the air volume flow generated by the compressor unit 3 using the control panel 19.

[0101] Furthermore, a user can start and / or stop the suction unit 5, particularly by manual input via the control panel 19. In addition, it is preferably possible to manually adjust the power of the suction unit 5 using the control panel 19.

[0102] Alternatively or additionally, it is possible to manually adjust the negative pressure generated by the suction device 5 and / or the extracted air volume flow using the control panel 19.

[0103] Preferably, one of the parameters, power of the compressor unit 3 and power of the suction unit 5, can be manually and / or automatically adjusted to the other parameter by means of the control unit 18.

[0104] For example, the power output of compressor unit 3 can be manually set by a user, and the control unit 18 automatically adjusts the power output of suction unit 5 to the power output of compressor unit 3. The reverse case, in which the user sets the power output of suction unit 5, is also possible.

[0105] Furthermore, it is preferably provided that one of the parameters, namely the power of the compressor unit 3 and the power of the suction unit 5, can be manually adjusted relative to the other parameter within an interval specified by the control unit 18. Thus, for a previously defined power value of the compressor unit 3, the power of the suction unit 5 can be manually adjusted and / or changed within a specified interval, or vice versa.

[0106] Preferably, at least one of the parameters – the magnitude of the overpressure generated by the compressor unit 3, the magnitude of the air volume flow generated by the compressor unit 3, the magnitude of the vacuum generated by the suction unit 5, and the magnitude of the extraction air volume flow generated by the suction unit 5 – can be manually and / or automatically adjusted to at least one other parameter by means of the control device 18. For example, the magnitude of the overpressure generated by the compressor unit 3 can be specified by a user, and the control device 18 automatically adjusts the magnitude of the vacuum generated by the suction unit 5 to the specified and / or current magnitude of the overpressure generated by the compressor unit 3. The reverse case, in which the user specifies the magnitude of the vacuum generated by the suction unit 5, is also possible.

[0107] Furthermore, it is preferably provided that one of the parameters, namely the magnitude of the overpressure generated by the compressor device 3 and the magnitude of the underpressure generated by the suction device 5, can be manually adjusted relative to the other parameter within an interval specified by the control and regulating device 18.

[0108] Furthermore, it is preferably provided that one of the parameters, namely the height of the air volume flow generated by the compressor device 3 and the height of the extraction air volume flow generated by the suction device 5, is manually adjustable depending on the other parameter within an interval specified by the control device 18.

[0109] In this way, the aforementioned parameters can be adjusted to each other manually and / or automatically, especially during the cleaning process, in order to enable a particularly even cleaning of radiator 2.

[0110] To achieve optimal cleaning results, the cleaning process preferably begins with the start of the suction unit 5, which draws in nearby dirt and / or dust particles. Subsequently, the compressor unit 3 is preferably started, particularly with a time delay, and an airflow is supplied to the radiator 2 from above. If the compressor unit 3 were started simultaneously with or before the suction unit 5, dirt and dust particles could be stirred up by the compressed air or airflow exiting the air nozzle unit 4 in such a way that they could enter the area surrounding the radiator 2.

[0111] At the end of the cleaning process, the compressor unit 3 is preferably switched off first, followed, preferably after a time delay, by the suction unit 5. This improves the overall cleaning process and results in no or less environmental contamination.

[0112] The holding device 8 preferably has a handle 20 to improve the overall handling of the holding device 8 and to facilitate the cleaning of radiators 2.

[0113] Preferably, the holding device 8 is designed for controlling, in particular for starting and stopping, the compressor device 3 and / or the suction device 5.

[0114] The holding device 8 preferably has a control element 21 for controlling, in particular for starting and / or stopping, the compressor device 3 and / or the suction device 5.

[0115] The control element 21 can, for example, be in the form of a push button, which can be used to start and / or stop the compressor unit 3 and / or the suction device 5.

[0116] The control element 21 is preferably electrically connected to the control and regulating device 18, in particular by means of an electrical cable. The electrical cable is preferably routed between the holding device 8 and the functional unit 10 through the flexible hose 13.

[0117] It is particularly advantageous if both the compressor unit 3 and the suction unit 5 can be started and stopped using the control element 21.

[0118] In particular, the control element 21 is designed to first start the suction device 5 and then the compressor device 3 during a cleaning process. For example, actuating the control element 21 can cause the suction device 5 to start and subsequently the compressor device 3 to start.

[0119] The control element 21 is preferably designed to first switch off the compressor unit 3 and then the suction unit 5 to end a cleaning process. For this purpose, the actuation of the control element 21 can be stopped or the control element 21 can be actuated again, whereby the compressor unit 3 is switched off first and then, preferably after a time delay, the suction unit 5.

[0120] Radiators 2 can have different heights. To easily adapt the holding device 8 to different heights of radiators 2, the holding device 8 is preferably telescopic, as already explained. To achieve consistently good cleaning even with different distances between the extraction unit 6 and the air nozzle unit 4, the control device 18 is preferably designed to adjust the output of the compressor unit 3 and / or the output of the suction unit 5 depending on the distance between the extraction unit 6 and the air nozzle unit 4.

[0121] Thus, the compressor unit 3 can provide a higher output for one radiator 2 than for another radiator 2 of a lower height. Simultaneously, the suction unit 5 can provide a higher output in the first case than for another radiator 2 of a lower height. In this way, an optimal and consistent cleaning result can be achieved regardless of the height of the radiator 2.

[0122] Alternatively or additionally, it is possible to adjust the level of the overpressure generated by the compressor unit 3 and / or the level of the air volume flow generated by the compressor unit 3 and / or the level of the underpressure generated by the suction unit 5 and / or the level of the air volume flow extracted by the suction unit 5 as a function of the distance between the extraction unit 6 and the air nozzle unit 4.

[0123] To optimally adapt the cleaning device 1 to each radiator type or shape, the air nozzle unit 4 and / or the suction unit 6 is preferably detachably, and in particular interchangeably, connected or connectable to the holding device 8. Depending on the radiator 2 to be cleaned, the air nozzle unit 4 and / or the suction unit 6 can then be exchanged for a differently designed air nozzle unit 4 and / or suction unit 6. For example, a first air nozzle unit 4 or a first suction unit 6 can be used for a first radiator 2. If a radiator 2 with a larger width B is to be cleaned subsequently, a different air nozzle unit 4 or a different suction unit 6 with a larger width B can be used.

[0124] Preferably, the air nozzle unit 4 has a coupling device 22 for connection to the holding device 8. Alternatively, it is also possible that the holding device 8 has a coupling device 22 for connection to the air nozzle unit 4. The air nozzle unit 4 can then be connected to or detached from the holding device 8 in a particularly simple and quick manner.

[0125] The air nozzle unit 4 and the holding device 8 are preferably connectable to each other in the context of a particularly linear assembly movement and / or detachable from each other in the context of a particularly linear disassembly movement.

[0126] Preferably the extraction device 6 has a coupling device 22 for connection with the holding device 8, or the holding device 8 has a coupling device 22 for connection with the extraction device 6.

[0127] Preferably, the extraction system 6 and the holding device 8 can be connected to each other in the context of a particularly linear assembly movement and / or can be detached from each other in the context of a particularly linear disassembly movement.

[0128] Alternatively or additionally, the air nozzle unit 4 and / or the extraction unit 6 can be individually telescopically adjustable in the width direction B of the radiator 2. In this way, the air nozzle unit 4 and / or the extraction unit 6 can be adapted to different radiators 2 with different widths B in a particularly simple manner.

[0129] It is possible to add a fragrance to the air volume flow generated by the compressor unit 3 in order to create a pleasant fragrance in the area of ​​the heater 2 during and, if necessary, also after cleaning, in order to support the cleaning effect through the fragrance and to give the user a pleasant feeling regarding the room climate.
